On mountainous sites, grade Ⅰ or Ⅱ stands including land below the crown of the secondary broadleaf forest and the Chinese-fir plantation or east-facing, shady dry land could be considered for the plantation. The transmittance of crown in the areas should be 55%~60%. One-year-old high quality seedlings above 25 cm tall and 0.25 cm in diameter near the ground-level should be used. For high-yield, field cultivation, shading facility should be considered and seedlings of taller than 15 cm and greater than 0.15 cm in diameter near the ground should be applied. The appropriate density and sunlight transmittance ought to be 30 cm×30 cm and 50%, respectively.

No differences in transparency, pH change or quanty of meperidine were observed either in accelerated tests at 40℃ or storage test for six months. Nevertheless, a decrease in pH value without significant changes of transparency and meperidine content was observed in accelerated tests at 60℃ after storage for 15 weeks. The pH value and meperidine content decrease significantly in both types of ampules when subjected to accelerated tests at 80℃ for 15 weeks.

The results showed:(1)Nitrogen addition changed the soil physical and chemical properties, enhancing the content of NO3—- N available resources in the soil, increasing the plants height and cover, reducing the vegetation light penetration. With increasing of N addition, both the species richness and the diversity decrease sharply (P 0.001).(2)N addition increased the aboveground biomass significantly (P 0.05). With increasing of N addition, the aboveground biomass increased first then decreased, and the grasses biomass increased while the forbs and legumes biomass decreased.(3)There was a significant linear positive relationship between species richness and vegetation light penetration (P 0.05), and also between aboveground biomass and soil NO3—- N content (P 0.05). The relationship between aboveground biomass and species richness was negative upon enhanced N supply.
